Specification of Letters Patent.

Patented Dec. 7, 1909.

Application filed February 9, 1909. Serial No. 476,879.

To all whom it may concern:

Be it known that we, JOSEPH APPLEBY and EDWIN APPLEBY, subjects of GreatBritain, residing at Tower Road, Aston, near Birmingham, England, haveinvented new and useful Improvements in Thread-Guides-forCotton-Spinning and Like Machinery, of which the following is aspecification.

This invention relates to thread guides and similar fittings for cottonspinning and like machinery, and has for its object to provide for themore expeditious and convenient adjustment of the guide or the like thanis aflorded by the appliances now in use.

The invention comprises the employment in conjunction with a suitableflap or holder, of a cam like or equivalent adjustment and locking pieceadapted to impart the required movements to the guide,,and also toreadily release the same when it is desired to completely withdraw theguide from the holder.

Referring to the two accompanying sheets of explanatory drawings :Figure1 is a front elevation and Fig. 2 a side elevation with the flapupturned, of a thread guide having this invention applied thereto. Fig.3 is a plan with the flap in its normal position and Fig. i a sectionalplan showing the guide actuating device. Fig. 5 is an inverted plan ofone of the flap members and Figs. 6 and 7 are respectively plan andcross section of the companion member, while Fig. 8 is a plan of themembers combined. Figs. 9 and 10 are plan and elevation ofa modifiedform of lower member for the flap. Figs. 11, 12 and 13 illustrate byplan, inverted plan and elevation respectively one form of guideoperating device, while Figs. 14, 15 and 16 are respectively similarviews of a modified form of such device. Fig. 17 is an elevation withthe flap upturned and Fig. 18 a longitudinal section of a flap havingapplied thereto a further modified form of guide operating device. Fig.19 illustrates in elevation an upturned flap in which provision is madefor lateral adjustment.

The same reference letters in the different views indicate the same orsimilar parts.

In carrying the invention into efiect, we prefer to construct the flapor holder from a pair of plates a b, suitably connected together to forma complete inclosure for the guide stem 0 and the adjustment and lockingpiece cl, and appropriately shaped to avoid objectionable angles orrecesses liable to promote the lodgment of dust or fly The holder may behinged as usual to a suitable bracket or rail. 1n the construction shownin the drawings each part a Z) is formed with a flange around thegreater part of its edge, the flange on a being deeper than that on Z).The flange on the latter serves to keep the elements apart at therequired distance while the flange on the former by being bent over theunderside of the other (as shown at Fig. 8) serves to secure the twoparts together. Fig. 5 shows the flange on a prior to the bending over.The lower part I) may be formed with a channel e to receive the stem 0of the guide as shown at Figs. 6, 7 and 8, or have attached thereto aseparately produced channel as shown at Figs. 9 and 10. Portions f ofthe hinge are formed on the part a while the corresponding portions areprovided on a bracket 9 adapted for attachment to the usual rail orboard. The flap is connected to the bracket by a hinge pin it.

Within the holder is mounted the rotatable adjustment and locking piece03 which in the form shown at Figs. 4:, 11, 12 and 13 is formed with anopen ended cam groove 2' of curved configuration extending from or nearthe center to the periphery of the piece. Beneath the adjustment andlocking piece ies the stem of the guide in the groove or channel in thelower plate of the holder, connection between the adjustment piece andguide stem being eifected by a pin or projection is which is formed asan integral part of such stem or is otherwise secured thereto. For therotation of the adjustment and locking piece a boss j from the latterprojects through the upper plate of the holder, and a slot is providedin the boss to permit its rotation by a key or like instrument. Onrotating the adjustment and locking piece a longitudinal movement isgiven to the guide and in consequence the latter can be very readilyadjusted to the required position. When the pin on the guide stem isadjacent to the open end of the cam groove, the guide is free to bedetached from the holder. By

virtue of the shape of the cam groove the adjustment piece serves alsoto lock the guide as the latter is incapable of being moved except bythe operation of the said piece. At or adjacentto the outer end of thecam groove a suitable shoulder or abutment Z or its equivalent may beformed or provided to limit the movement of the adjustment piece in onedirection by the abutment of the said shoulder against the pin is on theguide, or a stop on the holder itself. Vith such provision the movementof the adjustment piece is always arrested in the same position so thatthe guide can be immediately engaged with the adjustment piece on itsreinsertion in the holder after withdrawal. The slot in the cam showndoes not completely penetrate the member in which it is formed but isonly sufliciently deep to afford an effective connection With theprojection is on the stem 0. The upper surface of the cam is thereforeplain. In the adjustment piece shown at Figs. 14, 15 and 16, the lowersurface of the element at is formed with a projecting spiral or cam likeridge or depression extending through several eonvolutions, such ridgeor depression being engaged by the appropriately shaped end of theprojection fie aforesaid. This form of adjustment piece aflords a fineradjustment of the thread guide than the form shown at Figs. 4, ll, 12and 18. Instead of providing a number of convolutions as shown, a singleconvolution may be employed, and a series of projections formed on thestem of the guide.

Instead of a rotatable adjustment and locking piece, a sliding piece (Z(Figs. 17 and 18) may be adopted. The said piece is then arranged tomove transversely to the guide stem and to actuate the latter by asuitably inclined or otherwise shaped slot or groove 2' engaging withthe guide stem as aforesaid. The adjustment of the part (Z is effectedby a screw m passing through an internally screwed tubular part a formedwith the said part (Z.

Sometimes it is advantageous to provide for the lateral adjustment ofthread guides. This may be effected by the use (as in hinges heretoforeknown for other purposes) of a screwed hinge pin 0 (Fig. 19) arranged byits operation with a nut or internally screwed hinge portion 79 of theflap to move the latter with respect to the bracket. In this case asuitable space is provided as shown between the part p and the hingeportions of the bracket 9 to permit the required movement.

In the application of our invention we do not limit ourselves to anyparticular construction or disposition of our cam like or equivalentadjustment and locking piece nor to the manner of operating the same.When a key is undesirable, the rotatable piece may supporting {be madeof sufiiciently large diameter to project slightly through apertures inthe sides of the holder. It may be then actuated directly by the fingersof the attendant.

Having thus described our invention what we claim as new and desire tosecure by Letters Patent is 1.
